The brain of the system is the power module which can be interfaced via various communication protocols. The standard power module monitors trip status and provides remote reset for tripped circuits. The PROFINET power modules interface with devices at the cabinet and enable remote access to the device data. Remote capabilities make this system easy to monitor and easy perform maintenance from anywhere.
The CAPAROC IO-Link power module adds IO-Link communication to the CAPAROC customizable circuit breaker system. Customize your system to meet application needs and get real-time communication updates with IO-Link. Read and write current settings, reset tripped channels, lock the user interface, and much more with the easy three-wire connection. The CAPAROC power module with IO-Link ensures consistent protection and communication all the way to the field level.
1-channel modules are available with fixed and adjustable nominal currents, and 4-channel modules are available with adjustable nominal currents. The nominal current of individual channels can be adjusted remotely using the online interface or manually via the LED push-button operation.
The 2-channel modules allow you to easily read off the set nominal current directly on the device at any time. These modules can be individually adjusted from2 to 10A or 1 to 4A on the NEC Class 2 versions. Both are equipped with active current limitation to ensure a more efficient utilization of the upstream power supply. The active current limitation restricts short circuit and overload currents to a value that is 1.5 to 2 times the nominal current. This protects the power supply against excessively high currents and prevents output voltage dips.
The 0 V distribution modules are an ideal addition alongside every circuit breaker module. They allow the 0 V potential to be fed back directly via the CAPAROC system. The return conductor from every protected circuit can be conveniently connected in the system. Separate terminal blocks for 0 V distribution are no longer necessary. Blue color-coded pushers make it easy to differentiate between the 0 V and 24 V potentials.
The current rail ensures the safe and uninterrupted supply of power to the modules. Perform maintenance work at any time without interrupting operation. Unplugging individual modules only removes power to those modules. The rest of the system continues to operate and does not shut down. The CAPAROC system can be extended at any time to meet the needs of your application.
The CAPAROC circuit breaker system offers solutions for hazardous location applications around the globe. Our Class I, Division 2 rated parts are for use in North America. While our triple rated options are for use in the countries that require the ATEX or IECEx approvals.
NEC Class 2
CAPAROC circuit breaker modules rated up to 4 amps are approved in accordance with NEC Class 2. You can easily configure energy-limited circuits with CAPAROC and be safe from fire and electrical shock hazard. Instead of an NEC Class 2 power supply, you can simply install your high-performance standard power supply along with the CAPAROC system.
The online configurator helps you design an overcurrent protection system that precisely meets your needs. Each project contains a 3D model, detailed bill of materials, data sheet, and a unique solution ID, making it possible to re-enter the project to make changes or additions.
The orange nominal current assistant dials on the 2-channel modules allow load currents to be manually adjusted from 2 to 10A or 1 to 4A on the NEC Class 2 versions. The nominal current of the 1- and 4-channel modules are adjusted using single push-button operation.
CAPAROC is equipped with an electronic interlock for protecting nominal current settings. The set currents can be locked remotely or via the PWR LED button on the power module. By pressing the button and briefly holding it down, changes to the setting on the module are blocked.
The power module with PROFINET interface provides you with remote access to all device data and allows you to perform remote diagnostics and maintenance. With remote access, you can adjust or lock the individual channel current settings, turn them on/off, and even read the current flow.

Multi-colored LEDs ensure that the system state is transparent. Each circuit breaker module has one status LED per channel to indicate the current operating state of each channel.
The power module is the nervous center of the system. All data and signals are collected here and transmitted using either standard or PROFINET power modules.
CAPAROC cascades the start of all channels sequentially with a standard delay of 50 ms between the individual channels. This ensures that the load on the power supply is controlled and that all loads can be started safely.
All of the circuit breakers can differentiate between overload and short circuit to determine tripping behavior. The software differentiates between start-up and steady-state currents and responds rapidly via the electronics.
The 2-channel modules have active current limitation which restricts short circuit and overload currents to a value that is 1.5 to 2 times the nominal current. This eliminates the need to oversize your power supply, protecting it against excessively high currents and preventing output voltage dips.
The total current monitoring function ensures that long-lasting overloads do not occur. If an overload lasts longer than 2 minutes, the modules are disconnected sequentially, starting with the last channel on the last breaker to be connected.
The CAPAROC system easily integrates with PLCnext Technology. Remote access to control cabinets with CAPAROC and PLCnext enables a transparent view on the current status of plants and machines as well as easy remote maintenance from anywhere.
With the PROFINET (PN) power module, all system data can be queried via the integrated PROFINET interface. You can configure the channels and keep an eye on the current flowing, as well as read off past events from the error log.
The power module monitors trip status and provides remote reset for tripped circuits. The I 80% feature indicates if the load on a channel exceeds 80% of the nominal setting, so you can respond before a failure occurs.
The current rails connect the power module with every single module in the system. By connecting the supply line for positive and negative to the power module, the current rails are also supplied directly. You can swap out modules or perform maintenance and the rest of the system remains powered without downtime.
The structure of a CAPAROC system starts with the installation of an initial current rail with 8 or 20 slots. The individual modules are plugged onto the current rail and snapped into place. The system can be expanded with extension rails without the need for tools.
Power distribution modules allow the 0 V potential to be fed back directly via the CAPAROC system, decreasing wiring time and eliminating the need for additional terminal blocks. The blue color-coded pushers make it easy to differentiate between the 0 V and 24 V potentials.
